Hello @Leodog456 and welcome to the Help forums. I'm sorry, but the Interval Workout shortcut can only be set to time, not distance. You set the move time, the rest time, and the number of reps.
I believe that any Feature Suggestion requesting a change, like your distance or different move/rest times in one workout is listed as Not Currently Planned.
